It would actually be a great feature to also convert the word "bullshit" into a random keyword from the dictionary. This way you can run it twice and then generate brand new summary of the service.
The cool thing with this would be that after n iterations, where n % 2 == 0, you'd still get the same bullahit as output. Send this along with a hash/number indicating the position of each converted word in the dictionary, and you have a simple cipher thing.
